Racing Games - The Limited Slip Differential 

> Let's assume this car has perfect 50/50 weight balance > Shows me a Mustang Ure asking too much from me bruh

Mom: Why is there this doodely music in your room? Me: Im just watching a Video about LSD Mum: *throws her slippers*

Holy hell, finally someone explained it the way I can understand it. Btw watched it at 5am in bed with wife and kid... because you don't need sound on viperconcept video ;)

viperconcept please excuse me if I'm unclear but I'll try to explain what the center LSD is. The center LSD is just like the front or rear one (just imagine the front is the left and the rear is the right or the other way around), the only difference being the base power repartition. That base value is the most important, as it's the value the LSD will revolve around on both entry and exit. Keep weight transfer in mind, but only the front and rear part (we'll assume front and rear diffs are locked). For the low coast setting on braking the LSD will try to send the power to the rear wheels as there is the least resisting force and the car will OVERsteer as it will act like a hand brake or low brake bias: your car is now RWD. However, on exit with a low power setting, the car will UNDERsteer because the front wheels have the least resisting force and the LSD will send power on them: your car is now FWD. Then, like the other diffs it's inverted for high values (UNDERsteer on entry, OVERsteer on exit). I hope you have understood and if not I'll try to make it short here: for a 50(front)/50(rear) repartition if your center diff is open (low values) it can go from 100/0 to 0/100 and if it is locked (high values) it will stay at 50/50. If your diff is set at 45% power and 70% coast your car will go between 50-(50x30%)/50+(50x30%) on entry (100%-70%=30%) and 50+(50x55%)/50-(50x55%) on exit (100%-45%=55%). By the way I absolutely don't know what preload does on a center diff, but I highly thank you for explaining it on a front/rear diff, I finally understood !

Viperconcept you deserve an award for your videos, I’ve been following your instructional vids for years, you are also the reason I took the step to start racing online and make me become a respectfull, sportive and comptetitive driver. I am the type that watches those videos multiple times and take notes to test it out later, LSD has always been a tricky one, even after watching your first take on iT multiple times, this one is very clear and your efforts pay off more and more every time. Fun is always key. Thanks for everything and keep it up Sir. Carry on :)

Wow, we really need to thank GT Sport for their in depth HUD, really makes your tutorial videos really easy to understand

i feel like one day there is gonna be a video on a sim game about pebble physics and if they properly affect the car

This is the best tutorial I've seen on this. I've understood it from others before but this really gives us an intuitive understanding thanks to the focusing on the tyre load graphics live as changes were made. You can just feel how the forces themselves are working.

Love this type of videos. I always learn something. Keep up with the good content

Those Aston Martin _Drifts_ in the end were so Lovely. Great video as always Viper, you made it so easy to understand the LSD once and for all!...

Viper thx for your help, your just turned my Ford GT into a even better track weapon

Best description of the impact of LSD adjustments on handling on the net. Very nicely done. Thank you!

This is one feature I love with my Audi S4's sport differential. The car is solid when accelerating and turning. It give a new meaning to turning departures from a traffic signal.

best explanation on the entirety of RU-vid, Excellent work?

13:12 rip earphones

É por causa de vídeos como este que admiro e sigo este canal!

You got it the wrong way round on the PCARS2 LSD Accel, higher setting = 90 deg is no locking effect = understeer on RWD cars Lower setting = 20 deg is max locking = oversteer on RWD cars. Check the LSD ramp angle degree pictures online.

LSD is a drug too xD

Let's put it to simple terms: the LSD is a great tool to help the handling of your car. It gives you a lot of power to make the car behave the way you like. More acceleration lock gives you more predictability on gas, slightly less lock often gives more acelleration, but the point of losing the back gets harder to predict. The preload gives you mid corner oversteer, it makes the back tighter in faster corners and looser in the slow ones. If you like a kart-like feel you might want to try more preload. In projectCARS2, the stable setups often have less diff preload and acelleration lock to make the cars more neutral and better on the controller.

*How to tell if the Limited Slip Differential works* 1. Take any car that has an L.S.D. 2. Do a burnout/elevenses (burnout is the car not moving at all, but the wheels are spinning, elevenses is when you suddenly floor it from standstill, and an I I shape will be left behind due to the wheels rotating much faster than the the speed the car is moving at, and also, a burnout works best). 3. If the wheels rotate at the same time, the L.S.D does its job. If not, it needs a rebuild.

We are taking a more in depth look at LSD? cool now i have all the knowlege that i need to setup my LSD -farm-

Well here is a thing... When you did the coast demonstration, you did it with cars that have a lot of grip on the rear (on the rwd demo), but, for example, what if you take a car with street tires and skinny, like 205-225 on the back, and you put the coast number high, when you engine brake is actually going to create oversteer, the wheel with more weight is going to break traction because the tire doesn't have enough grip been skinny

Wow Viper, you are egineer, teacher and racer at the same time. Respect!

Hi! At 16:13 and 17:15 You wrote that we want to have same amount of TORQUE on different wheels. It's not right. We want to have same GRIP. And the same torque on all whells is only happens with free differential, no LSD. It's the only function of differential - to distribute torque evenly, even when one wheel is free spinning (torque on both wheels is zero)

LSD doesn't send more power to the outside wheel, it simply locks the driven axle. You're adjusting the LSD's propensity to lock the axles under different conditions

Hey Viper, nice video as always! Just wanted to point out 2 quick things on iRacing: 1) You didn’t feel a big difference changing the Drive Ramp Angle because you only had 2 clutch plates (more clutch plates = a more effective differential) and a very low preload setting. With more clutch plates, you’d feel a much bigger difference when adjusting the Ramp Angles. 2) The Cadillac isn’t a GT3 :) Keep up the good work man!

I wish I had teacher like Viper & more teachers like him !

Your video about setting is very useful.. I hope u can make more video about setting car 👍👍👍

LSD = the most important tuning adjustment you will ever make for racing games.

Thanks to you I finally understand how to set it up properly. Thank you!

You are a major help for noobas like me i always thought that preload has to do with some forces on differential part which means when the differential effect will take place faster or later but it is more that this and very coplicated as i see cause there is a difference between small and big cars well very good video it is a must see for many ppl who like to understand how these things works cheers mate

Merci beaucoup pour ces explications! Je connais bien le principe et le fonctionnement du DGL (LSD en anglais) mais je n'ai jamais réussi à faire de bons réglages en jeu. Ta vidéo va bien m'aider (surtout pour Project Cars 2) :)

God, I love your lessons so much! Viperconcept always delivers!

Super agradecido con esta clase! Gracias maestro! Saludos desde Venezuela!

Very informative video, along with all your other ones. You wouldn't figure that the LSD is part of stability and just as valuable as the suspension setup, but it's crucial for weight distribution for cars that are too light in the rear. Controlling the torque is just as important as distributing it, especially if your car lacks TCS, so at full throttle through a curve the wheelspin is greatly reduced. Pushing the drive tires to the ground using downforce, suspension, and LSD should work fine without the use of a TCS, since games like Forza give bonuses for higher difficulty settings.

These videos are educational as muvh as they are satisfying

LSD my favorite upgrade behind suspension and brakes its usefull in time attack just try it gives cornering traction braking traction people ignore but dont it helps u catch faster cars set faster lap times

In Project Cars 2 and iRacing the settings are actually the opposite - the smaller the ramp angle the bigger the locking effect and vice versa. 90 degrees = the LSD is actually disabled. And you have that thing written in the hint section on the right on the same screen where you state exactly the opposite...

Best vid out there on how Lsds work. Appreciate the video my bro

Is the interpretation of PC2 LSD against the in-game description in the tuning menu? It says lower ramp angels prevent inside tyres from spinning and send power to the tyre with more grip (outside) and 90 deg mean no locking at all, while you say "max setting (highest angle) = power to the outside wheel"

the first type of cars uses an open differential (O.D) the O.D problem was that it transfers most of the power to the wheel that lacks grip. For example, when you corner to the right at high speeds the wight will go to the left causing the lack of traction on the right wheel and spin the right wheel. On the other hand, the LSD transfer the power where it finds traction.

Good video. I found that for accel 10-15 were good ranges for control and optimum traction on RWD cars. 18-23 on FWD

Excellent work viper! Keep it like that. I hope you can make some videos with some basic setups for beginners at sims. Sometimes it is frustrating to change some things and not see some results. Hope you make some more championships because they are litt!

Before watching your video, I've been having a hard time understanding LSD. People keep saying cars with LSD is good, bla bla bla. Now after watching your video I finally understand what the hell is LSD!! Thanks viperconcept. Now time to turn on GT Sport and tune it lol.

Finally someone explained it well thanks dude

I am voting for adding Polish subtitles with using such words like: Wzdłużny balans obciążenia, Blokada wiskotyczna LSD, Szpula :D

Great video! Thanks viperconcept. Teach us more about different setup nuances! 😀

thanks Man . you deserve a like button now i understand something on the setup because i'm beginner on that. Please make a video about how to setup FFB and calibrate the wheel cause i have my first wheel racing the T150 ps4 pc . That's gonna help me a lot of.

Older games like Gt 2 which the game im currently playing on doesn't have this LSD, it works very differently

please do an explanation video(similar to this one) on all the car tuning setting and how to setup for all the sim racing games ; assetto corsa, project cars, iracing, raceroom experience, etc....

Great info bro..one of the best l.s.d info vids I've seen ! great work as usual bud 👍

Thank U very much for that lesson . I really learned alot & it made a big difference in my setups & lap times . . .

This lesson is a bookmark

Grazie mille per la spiegazione chiara e ricca di esempi pratici (come in tutti i tuoi video). Rivedendo il video non ho capito bene il precarico, in particolare il fatto per cui se alto l'auto è sovrasterzante in accelerazione. Se il precarico è alto non si ritarda la sua attivazione quindi per più tempo in curva e come se l'auto avesse il differenziale impostato a basso e quindi sottosterzante? Grazie

great job as always i'm wondering if you think these games are getting too detailed or complex in their settings for the majority of their players? is there such a thing as "too real" in that it makes it too hard for the average player to understand how to take advantage of them? and have you seen any games that have unnecessary settings or ineffectual ones?

Great video viper explained perfectly. Thanks

I tried it in GT Sport on my Porsche (991) RSR '17. I set the values ​​to maximum and minimum and tested both (to see the effects), but I didn't feel any difference in understeer or oversteer. Am I stupid or do I just have a good ability to adapt to the way cars drive? (Sorry, if my english is bad. I'm from Austria.)

Enjoyable and informative.

great vid! just a tip: hold shift while moving in free cam in assetto to move slowly :D

Hello viperconcept! First od all - sorry for my english, it's not very well becouse I am from Poland 😀 I need to say that your lessons about settings are verry usefull, helpfull and EASY TO UNDERSTAND to a lot of begginer drivers, and let them improve their skills. Keep working, very good job 😉. But i have a question, which of these setups should be done first, and which second/last. What is the sequence? Lsd, camber, anti roll bar, dumpers? Does it matter? Please help, i need Your opinion 😋

It's not a drug, it's Long Shore Drift.

Im learning more and more each time i watch yer videos, i may not be the best driver in game, but now i have a better grasp of it. I thank you for sharing yer knowledge

its only a game... by that theory you should care about wheel size/tyres diam. too...it gives diferent momentum/balance chasis force

Now that you've known about LSD, how about DMT?

Awesome video. Would love to see you explain LSD on Forza 7. Makes me wonder if LSD in F7 is broken or not.

Damn, I need to sit down with notebook and take notes. But I feel it’s worth it 😃

Damn, was just about to go schleep...

Next lesson: how to Viperconcept setup his AWD cars more in depth

Thanks a lot for all your lessons, it helped me so much!

Woah, this is a great guide, thanks....! This guide will be great for me as controller user.....

Nice lesson Viper, thank you!

So High power and low coast are the ideal settings for a FWD car?

I have one question: can the LSD be considered somewhat of an assistance? I mean, those settings can really solve some big problems while cornering...

Nice vid. Thanks. Although I do wonder why you don't just use your voice to narrate/explain. Would be quicker no ? But I like the chilled out style though 😋

Nice tutorial man! I have one question. There are many ways to adjust over/under steer. There is springs, anti-rollbars, damping, LSD, downforce balance. But how do I know which one to adjust? Like i feel like my car has oversteer, which should adjust first? Is there a way to know which part do I need to setup?

I think when we maximizing the amount of the power LSD both wheels will have the same amount of power just like a welded differential not just powering the outside wheel like you said on the video. please enlighten me if I'm wrong

Really useful, with my compliments! Good job.

@5:14 - Oh I know this corner... this will be fun lol

also from what i understand from the high and low coast is that the understeer from high coast happens cause engine brakes takes place slower so the car travels more to outside of the track while cornering its a time effect yes ?

That’s a hell of a drug

Nice, using Daisuke's gran turismo 5 jazz menu music

You just said that lsd preload helps maneuver, but what actually is it? Not just what it does?

Perfect video

This video explains it so well. Thanks!

Is wrong default setup of LSD reason why Mclaren MP4-12C feels so shitty to drive, compared to 458?

this video helped me a lotttt

My head hurts

Really helpful. Thanks man

Hey man, great video as usual. I'm wondering if you have any tips on being able to set consistent lap times because my driving style makes me fast but inconsistent which often screws up my strategy. Thanks

looks like we could say that 4WD cars are "addicted" to LSDs

How do you pause and "roam" around the car like that in AC?

is that first music from Metropolis Street Racer?

im so lucky for watching this tutorial

I really like some of your advice. But you are wrong about the LSD on Project Cars 2. A lower power ramp angle of 20° means more oversteer, on throttle. Especially when you add more clutches. A higher 90° Ramp angle will turn it off 100%. It also makes it much harder to power oversteer if you have an open differential (90° power ramp angle) on a rear wheel drive car. Maybe it's just the language barrier? I feel bad for saying this because you have helped me in the past. Maybe you could update the video?

Viper will you do another epic online championship on gt sport?

Tbh i've never experienced any downside putting the power diff. to min. in every situation in AC (unless you want to drift). Perhaps it's just my crappy sensibility.

Dude. You forgot the KANSEI DORIFTO?!? Weight transfer technique.

To know what this or that does, you need to maxed or lowered your settings one by one

Great video, very informative!!!

Amazing as always
